Slipknot bassist Paul Gray has been found dead in a hotel near Urbandale, Iowa. He was 38.

Police found no evidence of foul play in Gray's death according to the Des Moines Register but the investigation is ongoing. An autopsy and toxicology test will be conducted today to determine the cause of his premature death.

Gray's body was found by a hotel employee at around 10:50 EDT on Monday morning and witnesses report seeing items removed from his room early in the afternoon.

Slipknot's manager confirmed the death but did not offer further details.

Gray, known to fans as '#2' and 'The Pig', co-founded Slipknot in 1995 with drummer Joey Jordison and percussionist Shawn Crahan and the band released their debut 'Mate. Feed. Kill. Repeat' in 1996. The group has gone on to become one of the most successful and beloved acts in metal, earning legions of fans for their electric shows, over-the-top costumes and dark, anthemic brand of thrash music.

Their 2008 album 'All Hope is Gone' went to number one and the band, who have been nominated for seven Grammys, took home an award in 2006 for Best Metal Performance.

Gray had his share of troubles in the past. In 2003, he was arrested in Des Moines for possession of cocaine, marijuana and drug paraphernalia following a car accident.

But Gray seemed to turn his life around in recent years, reportedly marrying girlfriend Brenna Paul two years ago and recently expressing his delight at news of her pregnancy.
